feature: Support asset deletion via plugin

[malliaridis]

Is your feature request related to a problem? Please describe.

I am writing a plugin that allows the user to create and manage a set of assets (currently only colors). The plugin provides features of creating new and updating existing assets. When updating, there is the need of removing assets that are obsolete, e.g. when the plugin has a new release.

I couldn't find any function in the API that allows deleting existing assets from a local library (if such feature is present, please let me know).

Describe the solution you'd like.

I would like to have an option to delete generated assets.

The plugin is generating and grouping hundreds of assets, which are difficult to maintain manually. Therefore and for a better user experience, the plugin would provide the necessary actions for managing assets.

Describe alternatives you've considered.

Right now, the user can only delete assets manually by selecting the assets to delete. Deletion of grouped assets is not supported yet and the user has to expand the very first and very last asset in order to select theme with SHIFT (not obvious imo), and delete them then. This however does not solve the need of fully managing assets via plugins.

HI @malliaridis,

I am already developing a plugin that generates colors in the library. I faced this issue, but I resolved it by using the remove() method in the LibraryColor object. It was a guess, but it was worth it because it actually works! 😉

@madalenapmelo-kp The plugin API documentation does not mention this method in the LibraryColor, and the LibraryColor type from @penpot/plugin-types is not up to date regarding this. This returns a typescript error on my end.
